GONG OR BELL FOR SIGNALS;

Specification of Letters Patent No. 24,173, dated May 24, 18159.

To all whom it may concern:

Be it known that I, IsAAo F. VVooowARD, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Gongs or Bells for Railroad-Cars, Steamboats, Hotels, &c.; and I do hereby declare that following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters-of reference marked thereon.

Figure 1, is a perspective view of my improvement, (mounted on a block). Fig. 2, is a detached perspective view of ditto, minus the gong or bell. Fig. 3, is a detached perspective view of the escapement bar. Fig. 4, is a detached perspective view of the hammer or striking arm. Fig. 5, is a plan view of my improvement minus the gong or bell.

Similar letters of reference indicate corresponding parts in the several figures.

The object of my invention is to insure the striking of the bell at all times, and by simplicity of construction to diminish its liability to accident.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents the bed plate.

B, represents the escapement bar.

C, represents the hammer, or striking arm.

D, represents the gong, or bell.

On the bed plate A, and near the end there is a small round post (a) about two inches from the end of the bed plate A, and on a line with the post (a) there is a bell post (aa) finished with a screw on the top; about one inch from the end (a?) of the bed plate A, to the left of the post (a) (with the handle part of the block toward you) there is a projecting pin (ab), to the right of the post (a) about an inch and a quarter from the end of bed plate A, there is a projecting'pin (ac), having a fiat face diagonal with the bed plate A.

Near the end (1)) of the escapement bar B, and at right angles therewith, there is an arm to the end of the arm (0) there is attached one end of a spiral spring (CZ), near the end (6) of the escapement bar B, there is a slot (ad) through which a guide (ac) (having a head) is passed and riveted to the bed plate A, the end (6) of the escapement bar B, is finished in a rounded form, near the end (6) (of escapement bar B,) there is a semicircular recess terminating in a diagonal line (g) which in connection with the diagonal line (f) forms an angular projecting point (0) see Fig. 3.

Near the end (J) (and on its under surface) of the curved hammer or striking arm C, there is a projecting pin (is) and at a suitable distance from the end (J) there is a round hole made to fit loosely on the post (a) (of the bed plate A,) near end. the projecting pin (70) on the striking arm O, is allowed to slide into the recess (h) of escapement bar B, the detached end of the spiral spring is fastened to the hammer or striking arm C, at the proper distance required to bring the spring on a line, see Fig. 2.

The gong or hell D, is put upon the bell post (ac) and fastened in its proper relative position with a-nut (m) see Fig. 1.

When operating the bell, the angular face (f) of escapement bar B, slides against the angular face of the projecting pin (ac) on bed plate A, causing the escapement bar B, to move obliquely and (in connection with the spiral spring (6Z)) thus throwing it in and out of gear.

The various parts, can be made of such metals or materials as may be best adapted for the purpose. Owing to the complicated construction of the gongs or bells now in use, they are continually getting out of order, and it frequently happens that it is necessary to repeatedly pull the check string in order to make them operate, the inconvenience and danger of this defect will be readily appreciated. The simplicity of construction and the certainty of operation, must necessarily render my improvement very desirable.

Having thus described my invention, I do not wish to be understood as claiming any part as used in other gongs or bells, nor do I claim broadly the hammer or striking arm 0, but

WVhat I do claim as new and wish to secure by Letters Patent is,

The escapement bar B, constructed substantially as described, in combination with the end J, and pin K, of the hammer or striking arm G, the whole arranged substantially as described and for the purpose set forth.
